I must admit I'm quite shocked with that affirmative o.O I never actually looked to that item by that way, since when using the software I always looked at it not as a mainwindow containing a status bar which happen to have a QTabBar, but as a custom QTabWidget that had its tab offset and happen to have a status section in the area were it would have been otherwise. Maybe the view of the entire widget will change the solution?
